Final answer:
In Kaplan-Meier analysis, dichotomous yes/no answers are used, and participants cannot have recurrent events; letter c is the correct answer.
Step-by-step explanation:
In a Kaplan-Meier analysis, the probabilities of yes/no answers are used, and people enrolled in the study cannot have recurrent events. Kaplan-Meier curves are utilized to estimate the survival function from lifetime data. The Kaplan-Meier estimate is a statistic that allows us to estimate the survival probability over time in spite of censoring. The correct answer to the question posed by the student is therefore letter c. dichotomous; recurrent events.
The Kaplan-Meier analysis specifically takes into account the time until an event (e.g., failure, death, relapse) happens and the fact that not all subjects may experience the event during the study (censored data). Kaplan-Meier estimator provides a method of estimating time-to-event models in situations where not all subjects have equal follow-up times and some may not experience the event of interest at all during the observed time period.
